Specification of Letters Patent No. 26,365, dated December 6,11-859.

To all whom 'it may concern:

Be it known that I, Gr. W. MITCHELL, of Jackson, in the county of Madison and State of Tennessee, have invented a new and useful Machine for Operating Oar-Brakes; and I do hereby declare that the following is a clear, full, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a top view, Fig. 2 is a front view, and Fig. 3 a bottom view.

The nature of my invention consists first in a pair of beveled wheels the small one of which is placed on a horizontal shaft A as shown in Fig. 2, driven by the crank B. The large beveled wheel C is placed on a perpendicular shaft D and is driven by the small beveled wheel E. Also at the bottom of the perpendicular shaft D is placed a flanged or ratchet wheel F which ispermanently secured to the perpendicular shaft D and is operated by :a hooked pawlG which hooked pawl maintains the pressure ofthe attached to and operated by a springmplat` form J, which spring platform J hasta shaft in its center extending through the Hoor as shown in Fig. Qatl K, upon which` is placed a coil spring,` which `presses the platform J and pin I upward, which upward movement of the pin I relieves the brake.

What I claim as `my inventionand` desire to secure b Letters Patent is` 1. The anged or ratchet wheel and its hooked pawl as described and showninlFig.
